Check_MK Werk 5948: docker_container_mem: Docker container specific memory checking

ID: 5948 Title: docker_container_mem: Docker container specific memory checking Component: Checks & agents Level: 1 Class: New feature Version: 1.5.0i4 Instead of using the default linux memory check (mem), Check_MK is now using the container specific memory check. The main reason is that the memory information in the container is not available through <tt>/proc/meminfo</tt> as usual. The memory data is available through the kernels cgroup interface which is available in the containers context below <tt>/sys/fs/cgroup/memory/memory.stat</tt> The features of both checks are exactly the same.
